The TBI Field School Students visited the Kerio Delta this weekend.
We visited the Kerio Delta as part of the Ecology module, looking at some of the different vegetation types and learning about some of the species that live in the deltas of Lake Turkana. One of the most important and beautiful groups of insects that occur in the freshwater channels of the delta are numerous species of dragonflies. As we arrived at the edge of one of the delta channels, we found this beauty sunning itself. Dragonflies are aerial predators that eat mosquitoes and other insects that they catch in flight.
In the water below the dragonflies were numerous Whirligig Beetles. These are fast-moving beetles that swim on the surface of the water and hunt prey. The beetles are beautifully streamlined and swim about fast, whirling in crazy patterns when they feel threatened or disturbed.
